Acetylferrocene Flashcards
In what fashion does ethylene bind to d-block metals?
side-on fashion, donating electrons from the pi orbital into the d-orbital
Draw out the pi-bonding model of ethylene binding.
draw pg. 2
Draw out the cyclopropane model of ethylene binding.
draw pg. 2
Draw out the Friedel Crafts reaction using benzene and an acid chloride.
draw pg. 9
Draw out the Friedel Crafts reaction using benzene and acetic anhydride.
draw pg. 10
What is necessary for recrystallization?
molecule must be reasonably capable of crystal formation
What is necessary for distillation?
boiling point must be achievable without decomposition
What is chromatography useful for?
useful for small amounts and can be used to separate almost any mixture
What is the ideal Rf value?
Rf = 0.35
In normal phase silica, a more polar solvent means
more movement on the plate
In reverse phase silica, a less polar solvent means
more movement on the plate
What are three methods for TLC visualization?
iodine, KMnO4, fluorescence visualization
What is slurry packing?
solvent and silica are mixed and then added to the column
What is dry packing?
add silica gel to column and flow solvent through it until solvated
